The invention discloses an integrated circuit, an electronic device and a method for transmitting data in the electronic device to solve a problem of crosstalk in a printed circuit board. The integrated circuit includes a control circuit, a plurality of pins, and a plurality of driving units coupled to the pins. The control circuit provides a plurality of control signals according to data to be transmitted. The pins are coupled to a device via a plurality of conductive traces of the printed circuit board (PCB). The control signals control each of the driving units to selectively provide the data or one specific shielding pattern via the corresponding pin and the corresponding conductive trace of PCB to the device.
